Title: Wire feed systems for electric arc welding apparatus
Inventor: SPARK RONALD FRANCIS
IPC: B23K9/133
Filed: 1962-10-09
Abstract: 994,655. Lubricating. BRITISH OXYGEN CO. Ltd. Oct. 3, 1963 [Oct. 9, 1962], No. 38156/62. Heading F2A. [Also in Division B3] The movement of wire through a flexible conduit in a wire feed system for gas-shielded electric arc welding, is facilitated by blowing a powdered lubricant, e.g. molybdenum disulphide, into the conduit before passing the wire therethrough. A dispensing device for the lubricant is indicated in the Figure, and comprises a body 1 mounted at 2 on a wire feed unit, a nozzle 8 to which the conduit is temporarily coupled, an inlet 4 connected to a source of gas pressure, e.g. shielding gas, and a container 28 for the lubricant. The supply of gas through the inlet 4 and orifice 17 is controlled by a valve 18, biased to the closed position by a spring 20, having a stem 21 co-operating with an actuator 12. The member 12 is moved against a spring 10 to open the valve 18 when the flexible conduit is coupled to it. Further movement of the member 12 partially closes the orifice 17 to limit the amount of lubricant injected. The container 28 has ports 26 and 27, and a throttling member 29 establishes a pressure difference between the ports when gas is flowing through the orifice 17 so that gas flows through the port 26, fluidizes the lubricant, and causes it to be entrained in the flow out of the port 27 to pass through bores 31, nozzle 8, into the flexible conduit.

Title: Device for Digital Positioning, in Numerically Controlled Machines
IPC: G05B19/408
Filed: 1966-08-26
Abstract: 1,160,592. Programmed control of machine tools. LICENTIA PATENT-VERWALTUNGSG.m.b.H. Aug.26, 1966 [Aug.30, 1965], No. 38454/66. Heading G3N. In a numerically controlled machine, logic circuits are operable as stores for the actual position values or as an input shift register for series-introduced desired position values, a control deviation signal being desired from the position values by an arithmetic unit. As shown, a punched tape 1a containing a sequence of words, indicative of desired operations and digits of a position value in serial form, are read by a contact making reader 1b having an associated store 2. A decoding matrix 3 decides whether the contents of the store 2 is an address or a digit. The word addresses are decoded by a matrix 4 and supplied to a store 6 on an instruction from a central control unit 5 which controls circuit elements as shown by the broken lines. If the contents of the store 2 signify a digit they are transferred through a switch device 7 into the lowest decade of a logic circuit 8 operating as an input shift register. Subsequent digits are initially stored in the lowest decade, the contents of the register being shifted into the next higher values as the digits are fed into the circuit 8. The logic circuit 8 is also arranged to operate as a store for the parallel digit outputs of angle coding devices 12, 13 positioned by movement of a machine part. When a word signifies an operation, control of feed, spindle speed &c., the instruction passes through the unit 9 into stores 10, 11 to energize contactors in a power circuit 14 for the machine tool. A word signifying X, Y travel data is entered into the arithmetic unit at input A, from the logic circuit 8 operating an an input shift register, and the correction data, for machine and workpiece zero, from decade switches 15, 16 at input B. The corrected travel data is entered into stores 17, 18 and subsequently compared in the arithmetic unit with actual position data from logic circuits 8 now acting as a store. The cyclically determined X, Y errors from the arithmetic unit 9 are fed to stores 19, 20 which act on the power circuit 14, controlling, through couplings, the feed movements. The passage of the error through zero causes the couplings to be put out of engagement. Preliminary arresting matrices reduce the co-ordinate speed, through gearing, when the errors drop below predertermined values.

IPC: G01R17/08
Filed: 1956-12-27
Abstract: 878,292. Electric tests. SANGAMO WESTON Ltd. Oct. 24, 1957 [Dec. 27, 1956], No. 39318/56. Class 37. In an automatic control, detection or measuring system, deflection of the coil in a D.C. moving-coil instrument controls a reactive element in a transistor oscillator to vary the amplitude of the oscillations therein, and a current or voltage dependent upon the amplitude is developed which tends to balance the input current or voltage to the moving coil, the movement of which is thereby opposed. The moving coil of a D.C. instrument M is connected, in series with input terminals 1, 2, across a cold end compensating bridge network R2, R3, R4, R5, a thermocouple W being connected across the terminals 1, 2; and a ferrite plug f carried by the moving coil controls the L and Q values of a coil L incorporated in an oscillator driven by transistor T1, thereby varying the amplitude level of the oscillatory output. An applied E.M.F. from thermocouple W unbalances the bridge network, and the resulting deflection of the moving coil varies the amplitude level of the oscillatory output of T1 which causes the D.C. potential between the base and the emitter of T2 to vary, and the resulting collector current of T2, as indicated by instrument K3, provides a measure of the thermocouple E.M.F. The bridge components are arranged to supply a counterbalancing E.M.F. to terminals 1, 2 so that no current is drawn from the thermocouple. The input to the moving coil may be arranged to produce either an increase or decrease in the amplitude level of oscillation of T1. In modifications, the moving coil may carry a metal vane to vary the Q value of the tuned circuit L, C1; or the capacitance of C1 may be varied; and the instrument K3 may be replaced by a relay for automatic control or detection purposes. Specifications 700,643 and 786,481 are referred to.

Abstract: 890,535. Gas-blast switches. ALLMANNA SVENSKA ELEKTRISKA A.B. Nov. 20, 1959 [Nov. 24,. 1958], No. 39388/59. Class 38 (5). A gas-blast circuit-breaker comprises a compressed gas container 1 carrying at one end a fixed hollow contact 3 and at the other end a cylindrical casing 8 in which slides a hollow contact 4 joined by a rod 16 to a spring-biased piston 14 movable in a cylinder 15. Contacts 3, 4 are connected in parallel with auxiliary contacts 21, 22 and a resistor 23 by members 1, 8, 24, contact 21 being carried by a spring- biased piston 20 slidable inside contact 3. Contact 4 has spring-biased fingers 6 and an annular portion 11 co-operating respectively with a protrusion 7 and a flexible ring-shaped seating 12 on the contact 3, members 11, 12 forming a gastight seal. When the breaker is closed the inside of contact 4 communicates with the atmosphere through an open spring-controlled valve 13 and with the space 28 above piston 20 through a channel 26, thus allowing gas in space 29, charged from container 1 through a channel 25, to raise piston 20 against spring 27 to close contacts 21, 22. To open, gas from pipe 19 forces the piston 14 and contact 4 to the right and an arc-extinguishing gas-blast flows out through contact 4 and valve 13, after which the latter is closed by gas from cylinder 15 passing through a channel 30 to its interior. Opening of contact 4 allows gas to pass through the channel 26 to equalize the pressure in spaces 28, 29 and allow spring 27 to open the contacts 21, 22, the time interval between the opening of contacts 3, 4 and 21, 22 being determined by the size of the channel 26. To close, pipe 19 is exhausted to allow the spring 18 to operate the piston 14, movement of which connects the valve 13 to atmosphere through a channel 31. The closure of contacts 3, 4 and the consequent opening of the valve 13 allows the space 28 to exhaust to atmosphere and the closure of contacts 21, 22 to be effected by the piston 20.
